One other advantage of staging is that the contents are agnostic. You don't have personal photos up etc, so a new buyer doesn't subconciously feel its someone elses home and can not be theirs.
If you cant vacate the place then declutter , remove anything personal for the show homes like, used towels, toothbrushes, used soap, medication on bench tops etc etc. Just put them in the boot of your car for the duration of the show home.
